Compostos orgânicos voláteis (VOCs): caracterização e alternativas de remediação
(Universidade Federal de São CarlosUFSCarCâmpus São CarlosQuímica - Q, 2022-05-09)
Volatile organic compounds (VOCs) are present in human daily life, which can be emitted biogenically or anthropically. These are compounds that under environmental conditions have high volatility, they have a boiling point ...
VOCs abatement in adiabatic monolithic reactors: Heat effects, transport limitations and design considerations
(Elsevier Science Sa, 2016-12)
A simulation study of a monolithic reactor for the catalytic oxidation of Volatile Organic Compounds (VOC) over a Mn-Cu mixed oxide catalyst is presented. A heterogeneous 1D mathematical model is selected to describe the ...
Elimination of volatile organic compounds in paint drying by absorption reaction in water combined with the ozone oxidation technique
(Elsevier, 2020-10)
The aim of this work was to evaluate the treatment of Volatile Organic Compounds (VOCs) released during the painting and drying process of an industrial paint by absorbing them in a water curtain and then oxidizing them ...
Synthesis and characterization of manganese oxides employed in VOCs abatement
(Elsevier Science, 2005-10-27)
Two MnO2 were prepared by different methods: (i) MnCO 3 decomposition; and (ii) oxidation of acid MnSO4 solution. The combined use of X-ray diffraction (XRD), DRIFTS, DRS-UV-vis and TGA techniques revealed: (i) the presence ...
Recovery of manganese oxides from spent alkaline and zinc-carbon batteries. An application as catalysts for VOCs elimination
(Elsevier, 2013-04-04)
Manganese, in the form of oxide, was recovered from spent alkaline and zinc–carbon batteries employing a biohydrometallurgy process, using a pilot plant consisting in: an air-lift bioreactor (containing an acid-reducing ...
Study of the activity of Pt-Fe, Pd-Fe and Pt-Cu structured bi-metallic catalysts. Oxidation of VOC: toluene and ethyl acetate
(Facultad Experimental de Ciencias de la Universidad del Zulia, 2011)
Catalytic oxidation of aromatic VOCs with Cr or Pd-impregnated Al-pillared bentonite: Byproduct formation and deactivation studies
(Elsevier Science, 2008-05)
The catalytic behavior of chromium and palladium-impregnated Al-pillared bentonite for the oxidation of aromatic VOCs, i.e. chlorobenzene or xylene, was investigated. The Cr-impregnated bentonite showed high activity for ...
Catalytic oxidation of emissions in combustion systems for forest biomass, using catalysts with TiO2 support
(SOC CHILENA QUIMICA, 2006)
Catalytic combustion of volatile organic compounds in binary mixtures over MnOx/Al2O3 catalyst
(Elsevier Science, 2009-05-19)
In this work the catalytic performance of an alumina supported manganese oxide catalyst in ethanol, ethyl acetate, toluene and mixtures of them was studied. The reactivity of each VOC investigated increased in the following ...
